摘要

睡眠不足对睡眠依赖性记忆和情绪功能的有害影响已在现有文献中得到证实。然而,失眠引起的慢性睡眠障碍对情绪短期记忆的影响却很少被研究。21名患有亚临床失眠障碍(SID)的参与者和20名健康参与者(健康对照组,HC)进行了情绪面孔的延迟识别任务,并评估了在不同情绪状态下参与面孔记忆编码、保留和检索的事件相关电位(ERP)。行为研究结果显示,SID组的参与者有更大的反应偏差,与HC组相比,他们更有可能将负面面孔视为检索阶段出现的“老”面孔。ERP研究结果显示,SID组与HC组的情绪面孔在编码阶段诱导了显著较小的P1和晚期P3b和较大的N170振幅,在保留阶段诱导了较小的负慢波(NSW)。在恢复阶段,P1和早期P3b振幅显示了Group和Valance之间的相互作用,但Bonferroni校正后未发现组间差异。这些发现表明,睡眠失眠诱导的慢性睡眠障碍会影响情绪工作记忆的表现,并诱导情绪工作记忆中神经生理学的处理阶段特异性调节,而与价值无关。

Alternated emotional working memory in individuals with subclinical insomnia disorder: An electrophysiological study

The deleterious effects of sleep loss on sleep-dependent memory and emotional function have been documented in the current literature. Yet, the effects of insomnia-induced chronic sleep disturbance on emotional short-term memory have been scarcely investigated. Twenty-one participants with subclinical insomnia disorder (SID) and 20 healthy participants (healthy control, HC) performed a delayed recognition task of emotional faces, and event-related potentials (ERPs) involved in memory encoding, retention, and retrieval of faces across different emotional valences were assessed. Behavioral findings revealed that participants in the SID group had a larger response bias, being more likely to perceive negative faces as “old” faces presented in the retrieval phase than those in the HC group. ERP findings revealed that emotional faces in the SID vs. HC group induced significantly smaller P1 and late P3b and larger N170 amplitudes in the encoding phase and smaller negative slow wave (NSW) in the retention phase. In retrieval phase, the interaction between Sleep group and Valence were revealed for P1 and early P3b amplitudes, but no group differences were found after Bonferroni correction. These findings suggested that insomnia induced chronic sleep disturbance would influence performance on emotional working memory and induced processing phase specific regulation of neurophysiology in emotional working memory regardless of valence.
